SpoilerNo, Zinovia's not just being a bitch for no reason She has a 4d4+1 burning hands that is dying to fry bandits. So ideally she'd be able to hit a lot of bandits with that. I think the best place for her would be tucked in the area between A2 and the east wall. That way she can blast one side of the courtyard.
